Let's talk about how to balance wear and opportunity cost in trading, just two points: 1. Take die-hard bulls as an example: In the early stages of a bear market, minimize wear, as most opportunities are fake opportunities. 2. In the later stages of a bear market, opportunity cost becomes extremely valuable. It's better to accept wear for trial and error than to miss out on opportunities. 3. The same logic applies to breakouts after high volatility transitions to low volatility, and to breakouts after moving averages or patterns flatten out.
